Hi you all,

I have a very silly issue. I made a Multiple choice question Q1, with 2 options (just '1' and '2').
When I want to use this question Q1 in an if-statement, it always says Q1 is an undefined variable.
But it clearly is defined. Does any body know what I am doing wrong?
This is a simplified version of my issue.

I am very sorry cause this seems like a very basic issue but I've been trying to solve this for a long time.
I am using Version 4.1.18+200416.
Thanks in advance.

Multiple-choice questions do not exist as variables because they don't have columns in the data, their sub-questions have columns so those are the variables.
